An animal lover saw the dog abandoned at a gas station on Highway 11 and the Humane Society is looking for the owner.

The good Samaritan, who was identified as Lorie Hollis, told the Humane Society that she saw a man in the back of an old blue and white pickup truck deliberately drop off a dog at the gas station then speed away.

Witnesses said they saw the dog desperately trying to catch up with the speeding truck.

Calls were made to the local animal control office, which sent an agent to where the dog was last seen. Unfortunately, the dog was gone.

The dog was described as a black German shepherd mix with a small patch of brown under its neck.

According to a news release from the Humane Society, the owner abandoned the dog outside the gas stations and said, "Go! Go over there!"

“Appearing confused, the dog jumped up and put his paws on top of the tail-gate. The truck sped away, leaving the dog behind,” Hollis told the Humane Society. “The dog tried desperately to keep up with the truck as it sped away down the road. I got into my car and proceeded to follow as best I could.”

The dog continued to follow the truck, crossing two lanes of traffic, the release said.

After several miles, Hollis said she lost sight of the truck and the dog.

“My heart is broken, and I am in shock that someone would treat a dog like this,” she said.

"Unfortunately, we routinely receive these type of reports, where a dogs are dumped from a car or truck and left to fend for themselves along highways or back country roads,” said Jeff Dorson with the Humane Society. “As we know all too well, people can be cruel and heartless. If people feel they can no longer care for a pet, all they have to do is surrender him or her to a nearby rescue group or shelter, rather than abandon the poor animal at some random location, where their chances of survival are almost zero. This is truly a cowardly act and a punishable offense.”

The Humane Society of Louisiana is offering a $250 reward for information leading to the arrest and conviction of the owner or the safe return of the dog.

The Humane Society said it will accept custody of the dog and find it a home after the animal receives a medical exam and assessment.

The Humane Society is also asking for volunteers to canvass the area where the dog was last seen and to call its office if the dog is recovered at 888-6-humane.

"We would love to be a part of a happy ending for this poor dog. We believe that, working together, we can find this dog and provide him or her with a loving home and happy life," Dorson said.
